S7 TCP/IP

TCP/IP driver for Siemens Industrial Ethernet

OPC Client (Data Access)

• Compatibility with specifications DA 1.0 and 2.05a
• Connection to inproc, local or remote server
• Connection with up to 20 servers at the same time
• Monitoring of the connection to the server and automatic reconnection if the connection is interrupted.
• Address browsing if supported by the server.
• Benefits of the CALL-R functionality for CALL-R servers (simplified parameter assignment)

OPC Server (Data Access)

• Corresponds to Data Access 2.05a specification (reading/writing of online values).
• Is to be started as a manager just like other drivers.
• The provided DPEs (server -> client) can be easily and quickly defined via data point groups.
• DPEs can be declared as readable (read-only access is permitted; Group OPCRead) or as writable items (Group OPCWrite).
• Clients can browse the WinCC OA OPC Server hierarchically.

OPC Alarms & Events

OPC Alarms & Events (abbreviated to OPC A&E) is, in addition to Data Access, a further standard for performing central alarm management on a cross-vendor basis. OPC A&E is used to ensure the link to other control systems and the display of alarms/events in a hierarchical system.

OPC Historical Data Access

OPC Historical Data Access (OPC HDA) is used to exchange archived process data. This is in contrast to the OPC Data Access (OPC DA) specification that deals with real-time data.

OPC UA (Unified Architecture)

WinCC OA client supports the OPC UA Data Access (DA), Alarms & Conditions (AC) and Historical Access (HA) standards.

Modbus TCP

Modbus/TCP is based on the serial Modbus protocol, which was adapted for TCP/IP. The Modbus/TCP driver can be used simultaneously for Modbus/TCP or UNICOS.

Ethernet/IP

Ethernet/IP is used for communication with several PLC generations and families from Rockwell Automation / Allen Bradley. The protocol is part of the application layer and is based on the standard TCP/IP network protocol.

S-bus

The WinCC OA S-bus driver is used to link SAIA PCD control devices to WinCC OA projects. Client mode of the SAIA S-Bus driver is used. Communication is carried out using the UDP; the serial version of the protocol is not supported.

Serial: RK512/3964R

Is used for interfacing a PLC via the 3964R/RK512 protocol

Cerberus

Cerberus is a fire, intrusion and gas alarm system. The Cerberus driver guarantees communication to and from the central fire alarm systems and building security facilities in the event a fire, gas or intruder alarm.

SSI

Is used for the interfacing of SAT remote control systems. The data is exchanged via the LAN (Ethernet, IEEE 802.3); the frame formats used are the SSI formats defined by SAT. The SK 1703 telecontrol components with a suitable communication card (KE/ET) are supported.

IEC 60870-5-101, -104

IEC drivers are standardized telecontrol drivers that can process proprietary frames. IEC stands for International Electrotechnical Commission, the international standardization committee for electrical engineering.

• IEC 60870-5-104 for data exchange via TCP/IP
• IEC 60870-5-101 for serial connection

IEC 61850/61400

IEC 61850 Client and IEC 61400 Client defines an architecture for satisfying the requirements of electrical substation automation. It defines a data model and the communication services for interaction with and between the elements of a substation, such as power supply units, circuit-breakers, protective devices etc. A description language and a system configuration language (SCL) have been defined for technical purposes.

DNP3

The DNP3 (Distributed Network Protocol 3) driver is an open, rugged and modern protocol which exhibits characteristics and strengths similar to the IEC driver. The transfer of any number of frames with different data types takes place between the WinCC OA System (Master) and the remote stations (Slave).

SINAUT

SINAUT (SIemens Network AUTomation) is a communication protocol for automated monitoring and control of remote process stations on the basis of SIMATIC S7. Communication takes place via TCP/IP.

SNMP Manager & Agent

SNMP (Simple Network Management Protocol) is a protocol for monitoring network elements (servers, workstations, routers, switches, hubs, etc.) and their functions.

• SNMP Manager supports SNMP V1, V2, and V3
• SNMP Agent supports SNMP V1 and V2

BACnet over IP – driver

BACnet (Building Automation and Control Networks) is a standardized protocol for building automation and has been set by the ASHRAE (American Society of Heating, Refrigerating and Air-conditioning Engineers) as a guideline to provide a uniform and cross-company standard for data communication within and between building automation systems.

The BACnet Standard 2004 is supported in accordance with the PIC list (see product documentation)
